Title: Improvements in the manufacture and production of artificial masses containing casein
Filed: 1927-05-23
Abstract: 297,483. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 23, 1927. Casein; formyl and acetyl ethanolamines. - Artificial horn is made by incorporating with casein liquid or solid hydroaromatic or aliphatichydroaromatic amines, or such aliphatic amines as contain hydroxyl groups, or salts or derivatives of such amines. Aliphatic-hydroaromatic amines which contain hydroxyl groups are particularly suitable, such as cyclohexylethanolamine, cyclohexyldiethanolamine, and their homologues, which in small proportions facilitate the plastifica-tion and clarification of the casein even at ordinary temperature. Aliphatic-hydroaromatic amines containing hydroxyl groups may be obtained by the process of Specification 297,484. Acyl derivatives of the specified amines, such as formyl ethanolamines (obtained by the action of ethylene oxide on formamide), or salts of the specified amines, such as the carbonates, acetates, and lactates, may also be used, cyclohexylamine acetate being mentioned. Many of the specified amines or their salts and derivatives (such as acyl derivatives) are soluble in water, which facilitates their use. In art example, moistened casein is intimately mixed with a small proportion of cyclohexylmonoethanolamine or cyclohexyldiethanolamine, or a mixture of these amines of their salts or acyl compounds, the mass being moderately heated under pressure.

Title: Improvements in or relating to radiators and like heat exchanger devices
IPC: B21D53/04
Filed: 1965-04-01
Abstract: 1,100,445. Producing radiator nests; brazing. SOC. ANON. DES USINES CHAUSSON. 1 April, 1965 [17 April, 1964; 24 June, 1964], No. 13950/65. Heading B3A and B3R. An aluminium radiator nest is produced by preparing a number of elements 1 each formed by two superposed sheets defining chambers 7 joined by ducts 4, the sheets being coated with an aluminium-silicon alloy, assembling the elements into a nest with spacers interposed between adjacent elements, and dipping the nest into a flux bath to join the spacers and elements together. An outer casing and appropriate fittings may be brazed to the nest at the same operation. Passages 2, Fig. 5, are subsequently produced where the chambers 7 of adjacent elements join each other. The elements are conveniently produced by roll bonding two sheets together after coating with an appropriate pattern of stop weld, the chambers and duets being formed by fluid inflation using passages 5. Alternatively, half shells may be stamped for each element, the shells then being soldered or otherwise fastened together. These passages-are fully or partially closed before the dipping takes place, so that flux is unable to enter the chambers 7. The brazing can, if desired, take place in a furnace after the step of coating the nest in a bath, the temperature of the furnace, or alternatively the flux bath where this is used alone, being about 600‹ C. The abutting surfaces of the chambers 7 of adjacent elements can be formed with co-operating annular projections and a ring of aluminium-silicon make up metal may be positioned between the adjacent elements. The passages 2 passing through the elements may be produced by laser beams, an electroerosion process or by conventional machining.

Title: A heatable glass sheet
Inventor: WOELK HUBERT
IPC: H05B3/84
Filed: 1970-03-23
Abstract: 1276979 Electrically heated windows COMPAGNIE DE SAINT-GOBAIN 23 March 1970 14037/70 Heading H5H A heated window 1, e.g. for automobile vehicles, with a network of resistance strips 2 is characterized by an indicator strip 8 including a substance sensitive to temperature variations and placed adjacent the strips 2 to furnish evidence of functioning of the strips by modifications in its appearance. If strip 2a is out of service, the colour, for example, of the indicator strip 8 is different adjacent this strip 2a from its colour adjacent the other strips 2, see also Fig. 3 (not shown). Using cobaltous chloride as the active substance, its hydrated form, stable in the presence of normal atmospheric humidity, possesses a pink colour, which a temperature rise changes to blue as a result of drying. Other possible substances are cobaltous iodide or complex salts of cobalt and pyridine. Strip 8 may be an adhesive removable strip or may be patches of lacquer near to one end of the strip 2. The colour change is reversible. Polymers and water combined produce a product which becomes cloudy when its temperature passes a certain value and becomes clear again when the temperature drops, and this may be used as the active substance of the indicator. The strips 2 are layers of a fired conducting silver paste electroplated with nickel after firing. Specification 1,145,367 is referred to.

Title: Improvements in or relating to conveyor means for confectionery moulds or other articles
IPC: B65G23/40
Filed: 1956-05-10
Abstract: 788,499. Step-by-step conveyers. BAKER PERKINS, Ltd. May 10, 1956 [May 18, 1955], No. 14552/56. Class 78 (1). A conveyer means comprises endless conveyer chains H, I, which are driven such that each article is confined between a lug 18 on one chain serving as a retaining lug and a lug 21 on the other chain serving as a pushing lug whereby each lug serves alternately as a pushing lug for one article and then as a retaining lug for the next article. As shown, moulds A, B, C containing rows of cavities 3, 4, 5 are pushed by chains H, I step-by-step under a row of nozzles 67 from which material is fed from hopper G. The chains derive their movements from respective ratchet units 100 and 101. Ratchet unit 100 includes a ratchet 60 and ratchet 38. Ratchet unit 101 includes a ratchet 37 and ratchet 59, the ratchet unit 100 being freely mounted upon shaft 42 and driving chain I through sprocket 49, chain 50 and sprocket 51, and ratchet unit 101 being fixed to shaft 42 and driving chain H through sprocket 43, chain 44 and sprocket 45. Pawl 36 drives both ratchets 38 and 37, whilst pawl 57 drives ratchet 59 and pawl 58 drives ratchet 60. Pawls 57 and 58 derive their movement from follower 54 governed by cam 30, whilst pawl 36 derives its movement from the follower 32 governed by cam 29, both cams being continuously rotated by driving shaft 28. Each ratchet unit therefore receives a separate movement from each of the two cams which causes the chains to push successive moulds in turn and also to compensate for the space between moulds.
